Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to an incorrect offset calculation in the Linux kernel, specifically in the erofs/zmap.c file. This miscalculation resulted in the iomap->length being set to 0, triggering a WARN ON in iomap iter done(). The problem was initially reported as a crash by syzbot due to a warning encountered in iomap iter done(), although it was unrelated to erofs.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
